Carbonate hydrogenation to formate is a promising route to convert captured carbon dioxide into valuable chemicals, thus reducing carbon emissions and creating a revenue return. Developing inexpensive catalysts with high activity, selectivity, and stability remains challenging. We report a supported non-noble metal catalyst, Ni/TiO , with great selectivity over 96 % and excellent stability in catalyzing the conversion of carbonate into formate in aqueous solution. Ni and Ni species are both observed in Ni/TiO catalysts, and the synergistic effect of these two Ni components leads to high activity and high selectivity of carbonate hydrogenation to formate.
将二氧化碳加氢转化为甲酸盐是一条将捕获的二氧化碳转化为有价值化学品的有前景的途径，从而减少碳排放并创造收益回报。开发具有高活性、高选择性和高稳定性的廉价催化剂仍然具有挑战性。我们报道了一种负载型非贵金属催化剂Ni/TiO，在催化水溶液中碳酸盐转化为甲酸盐的过程中具有超过96%的高选择性和出色的稳定性。在Ni/TiO催化剂中同时观察到了Ni和Ni物种，这两种Ni组分的协同作用导致了碳酸盐加氢转化为甲酸盐的高活性和高选择性。
